Specification of Letters Patent.

Patented July 28, 1914:.

Serial No. 800,357.

To all whom it may concern Be it known that I, Bron B. Fanxnaar, acitizen of the United States, residing at Buffalo, in the county of Erieand State of New York, have invented a new and useful lVlixing-Machine,of which the following is a specification.

This invention relates to a mixing machine.

An object of the present invention is to provide a I'IltIClllllO whichwill mix different kind of grains in certain and definite proportions.

A further object is to provide a machine which will mix grains indefinite proportions and will supply to the grain so mixed a definiteamount of liquid such as molasses and will. agitate and thoroughly mixthe heterogenemls mass to substantially uniform constituency.

A further object is to provide an apparatus including a number ofpositive feed supply valves which are adapted to measure certainquantities of grain or allied material in a given time, to thoroughlymix the grain, and to provide a liquid measuring valve which will supplya predetern'iined amount of liquid to the aforementioned mixture and toprovide a mixer which will thoroughly agitate the heterogeneous mass anddeliver the same at a substantially uniform rate.

A further object is to provide an apparatus of the class above mentionedwhich includes a mixing chamber with a plurality of angularly disposedplates therein and which contact with the inner periphery thereof sothat there will be no likelihood of the material building up and cakingon the side walls of the mixing chaml'icr. For the above mentionedreasons also the spiders are provided in the end walls oifthe mixingchamber and take the place of the usual shaft, the spiders contactingwith the end walls maintain the same in a plane and free condition.

W'ith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made Within thescope of what is claimed, without departing from the spirit of theinvention.

In the drawings accompanying this specification and forming a partthereof, the preferable form of my invention is dis closed, whereinFigure 'l is a side view in elevation with parts thereof broken a 'ay,illustrating my improved mixing machine. Fig. 2 an end view thereof.

Referring to the drawings in which similar reference numerals designatecorrespond ing parts throughout the several views, 3 is a storage binfor grain or allied mate rial and which is provided with a plurality ofcompartments therein defined by the partitions t. Mounted beneath thebins, sup- 'icrting the same and communicating therewith are thepositive food supply valves 5 which are formed with a casing (3 whichhasthcinlet 7 and outletta' communicating therewith. A shaft 9 extendsthrough the valves and is provided with the nuasuring rotors 10 whichrotate within the casing and are provided with the buckets orcompartments 1.1 which come in alincment with the inlet 7 and crmvey acertain definite quantity of material around the casing and deliver thesame to the outlets S. A somewhat similar valve is illustrated at 12,which valve however is for the supplying of a certain quantity of liquidand in addition the shaft .13 and rotor 14- includes an inlet liquidsupply pipe 15 and outlet 16. A valve 17 is positioned within the liquidsupply pipe and is used to close the pipe during the non-use of theapparatus. A vent pipe 18 communicates with the casing at its upper andlower extremities adjacent the inlet and outlet thereof so that theliquid will [low freely into the compartments of the rotor and will flowas readily there from.

A casing 19 is provided with a shaft 20 extending axially thercthrmighand upon which is mounted the worm conveyor 21. The casing 19 supportsthe valves 5 and 1.2 thereabovc which communicate therewith. Positivedriving means 22 extend between the shafts 9, 13 and 20 so that am-edctermined ratio may be had between the amount of grain fed by thevalve. 5 and the quantity of liquid supplied by the valve 12. Theconveyor casing 19 is provided at its front end with a hopper 23 throughwhich the mixture of grains and liquid pass.

The heterogeneous mass of mixture passes through the hopper 23 down intoa mixer which includes the casing 2 L, cylindrical in outline, androtatably secured to the ends of which are the stub shafts 25. Oneextremity of the mixer casing is supported by the post or beam 26 bywhich the entire device is anchored to the ground and the mixer casingis held against rotation. The remote extremity of the mixer casing 2a issupported by the stub shaft 25 which is journalcd within the postbearing 27 A pulley wheel 28 is secured to this stub shaft and isadapted to impart rotation thereto from some suitable source of power,not illustrated. The stub shafts extend through the cas ing ends andhave the spiders 29 rigidly secured thereto which are adapted to rotatetherewith. Bars 30 extend between the outstanding legs of the spidersand to which bars are secured the angularly disposed mix ing plates 31which are adapted to move the contents of the mixing chamber from oneend to the other to thoroughly agitate and mix the same to therebyproduce a mixture of practically uniform constituency. In thisconnection it is to be noted that the ends of the agitating plates 31contact with the inner peripheral surface of the casing 24: so thatthere will be no likelihood of the material c-aking upon the side wallsof the casing which would obstruct the free working of the apparatus.Also mention is made of the fact that in some instances a single row ofthe plates 31 may be turned in the opposite'direction so that they willforce the mixture i a. reverse direction, it being noted that themajority of plates however will be turned so that the mixture will begradually worked toward the outlet end of the mixing chamber. This isillustrated in Fig. 1 of the drawings in which the lower most one of theplates 31 is inclined at a different angle and in the opposite directionthan the two upper rows of plates. The lower portion of the mixingcasing and at the end remote from the hopper 23 is pro vided with theoutlet door 32 through which the thoroughly agitated mixture passes. Theend of the mixer casing adjacent the hopper 23 is hingedly secured tothe said casing as at 33, there being a suitable latch to hold the sameagainst accidental detachment. The end of the casing may swing about thehinge 33 without hindrance from the stub shaft 25 by reason of the factthat the bearing between the stub shaft 25 and the said end is oflimited length to allow the operation to take place as described.

The beams 35 extend between the mixer casing and the conveyer casing forthe supporting of the latter and to insure that the entire machine willbe of rigid and strong construction. The machine herein disclosed isintended to be used with grains which are to be coated or covered withmolasses although it is to be understood that it may be used for otherpurposes with equally cilicient results. The gear. ratio between theshafts 9, 13 and 20 may be varied so that the final mixture may containthe various ingredients in any desired proportions, the above holdingtrue also with respect to the amount of molasses or liquid suppliedthrough the valve 12. The shaft 13 of the valve 12 is provided with theclutch 36 so that the said valve may be temporarily stopped should it beapparent that the mixture contains a too high percentage of the molassesor liquid. The material within the bin 3, usually grain or other similarmaterial, is fed down through the positive feeding valves 5. The size ofthe buckets of the valves may be changed so that any desired valves maybe changed so that any desired mixture of the grains can be obtained.The grains pass down into the conveyer casing 19 along which they aremoved and agitated so that a thorough mixing thereof is had and, whichmixture passes into the hopper 23 located directly beneath the molassessupplying-valve 12. The buckets of the rotor of the valve 12 may also bechanged so that the quantity of liquid or molasses may be varied or therelative speeds of rotation of tl-e valves 13 and 5 may be varied toproduce a like result. The mixture of grains and molasses passes downinto the mixing casing or chamber 24 wherein it is thor- (mghly agitatedand gradually moved from one end of tie casing to the other and in whichprocedure the grains become thoroughly coated with the molasses.

Having thus fully described my invention, what ll claim is 1.
